What is a DUI checkpoint?

DUI checkpoints, also known as sobriety checkpoints, are roadblocks set up by law enforcement to stop vehicles randomly and check drivers for signs of intoxication or impairment. The primary goal of these checkpoints is to deter driving under the influence of alcohol or drugs by increasing the perceived risk of arrest.

Legal basis for DUI checkpoints in Pennsylvania

Under state and federal law, DUI checkpoints are legally permitted in Pennsylvania, including Chester County. The U.S. Supreme Court has ruled that the intrusiveness of DUI checkpoints on individual privacy is outweighed by the public interest in reducing alcohol-related accidents. In Pennsylvania, this practice is specifically authorized under state law, and all operations must adhere to guidelines that ensure transparency and fairness.

How do Chester County DUI checkpoints work?

Planning and publicity

Chester County law enforcement agencies must publicly announce the general area and time of DUI checkpoints in advance, although specific locations and times are not always disclosed. This publicity is intended to deter drinking and driving.

Selection of vehicles

Vehicles are stopped according to a predetermined formula, such as every third vehicle, to prevent claims of bias or targeting.


Drivers of selected vehicles are briefly interviewed and observed for signs of impairment. Officers typically look for slurred speech, the smell of alcohol, or visible signs of drug use.

Field sobriety tests

If an officer suspects that a driver is under the influence, they may conduct field sobriety tests. Further action, such as a breathalyzer test, may be required if these tests indicate impairment.

Detention and arrest

Drivers found to be impaired may be detained, and based on the results of breathalyzer or chemical tests, further legal action may follow.

Your rights at Chester County DUI checkpoints

Knowing your rights at a DUI checkpoint is crucial. At Kellis Law Firm, we emphasize that while you must comply with law enforcement:

  • You have the right to remain silent. You are not required to answer incriminating questions.
  • You can refuse to perform field sobriety tests, although this may lead to further legal actions such as mandatory chemical testing under Pennsylvania’s implied consent law.
  • Checkpoint officers should treat you with respect and without discrimination.

How to handle a stop at a DUI checkpoint

Remain calm and polite if you are stopped at a Chester County DUI checkpoint. Provide your license, registration, and proof of insurance upon request. If you feel your rights have been violated, note the details, but avoid confrontations with officers. Instead, contact Kellis Law Firm as soon as possible to discuss your case and explore your legal options.
